From 31def32eeed8cff705ca827e4bbc0bfcc80c512f Mon Sep 17 00:00:00 2001 From: NIIBE Yutaka Date: Mon, 26 Oct 2020 11:38:47 +0900 Subject: [PATCH] scd: Internal CCID driver thing only for SPR532. * scd/ccid-driver.c (ccid_vendor_specific_setup): New. Limit only for SPR532, excluding other readers by SCM. (ccid_slot_status): Use ccid_vendor_specific_setup. -- We follow the setup procedure of libccid implementation, which sends the escape command for SPR532 only.
